0404.10.20.00 - Fluid

This HTS category, 0404.10.20.00, specifically covers "Fluid" whey and modified whey products that are not dried. This includes liquid forms of whey and modified whey, irrespective of whether they contain added sugar or other sweetening matter. Modified whey, in this context, refers to whey that has undergone specific processing to alter its physical or chemical properties beyond simple concentration. The key defining characteristic for inclusion here is the liquid state of the product.

This classification distinguishes itself from its sibling category, "Dried," by the physical form of the whey or modified whey. While both fall under the broader heading of whey and modified whey, products classified here are in a liquid or fluid state, whereas the sibling category encompasses products that have been dehydrated. This distinction is crucial for customs purposes as it reflects different processing methods and potential uses.

As this is a leaf node within the HTS, there are no further subcategories. Therefore, the classification is finalized at this point, meaning any fluid whey or modified whey product not elsewhere specified or included within Chapter 4 that does not meet the criteria for dried products would be classified under 0404.10.20.00. Examples would include fresh liquid whey, or concentrated liquid whey that has not undergone a drying process.
